I only watched about half the video, however I would guess that the heat treating of the valve seats caused the head to warp. It's evident that the heat treating happened after the head was originally machined due to the visible heat affected zone. This would make sense since the cutter was only cutting on the outer edges of the of the head, the heat treating caused the metal to shrink when it cooled resulting in the outer perimeter to draw up and creating a dish.

Good techs like you are hard to find. If that was done at a dealership I would bet that they would just toss them on the truck and be done. Then when you come back in 6 months with a blown head gasket they would be quick to blame a tune or something else. With the customer not even knowing that the heads where faulty to start with.

Yes the warp was within "spec". But are you gonna line up and feel good about a thousand bucks for the part and have confidence when you lean on the skinny pedal??? Not me. I have a phrase,,, it's a lil cocky,, But "perfect is the benchmark". Btw that head was inconsistent with the last head I got from Ford. Both of them are video documented. The last one had a good surface but was .014 below the 3.74 spec. Ford says the heads are not mill able, but I walked out of the dealership with a head that was 3.726. So I opted to not shave that one.

That is why the Ford techs hands were tied when repairing a vehicle, even OEM parts were trash.
